Brief summary

The investigator(s) hypothesize that Rituximab together with combination chemotherapy, followed by Rituximab maintenance therapy, will provide better disease control with improved response rates and overall survival in patients with previously untreated Mantle Cell Lymphoma (MCL).

DRUGLeucovorin

Leucovorin 100 mg/m\^2 IV beginning 36 (+/-4) hours after start of Methotrexate infusion, and then 10 mg/m\^2 at 6 hour (+/- 30 min) intervals until Methotrexate level is \< 0.1 µmol/L during Cycles 1 and 3.

DRUGMesna

Mesna 360 mg/m\^2 IV on Days 1 through 5 of Cycles 2 and 4.

DRUGMethotrexate

Methotrexate (MTX) 1,200 mg/m\^2 in 250 mL with Dextrose 5% in water (D5W) IV over 1 hour, followed by Methotrexate 3,000 mg/m\^2 in 1,000 mL D5W by continuous infusion over 23 (+/-2) hours on Day 10 of Cycles 1 and 3.

PFS is defined as the time in years from start of treatment to the earliest one of the following events: relapse (in patients who achieve complete response), disease progression (in patients with partial response or stable disease), or death. PFS will be evaluated by treating physician from staging Computed Tomography (CT) or Positron Emission Tomography (PET) scans.
